Never had to deal with this problem but.....If you have made adrs for 3 and ended up with only 2 going...do they give you a problem? This COULD be a problem as we get closer to trip....but Id hate to have to do adrs all over again with chance of losing what we have. I know one problem is that if they knew was only 2 could have given you table for only 2 but from what Ive seen Most tables will fit 3-4 anyway.
